  • 1) Introduction

    Often, when you build a website, you want columns.

    Common designs include

  • I've got those 3 button mice from SGI as I was working with Indy's and O2's. I also have keyboards. Those are real good quality!

    Yesterday, I tried to right click and somehow, nothing happened. At first I thought maybe it was X going banana, but trying again and restarting did not change anything. I reset my KVM too, just in case. Still nothing.

  • Ada variables are complex objects. When developing a compiler, you must definitively take that in account. You have several sides to your variables: one you need to be able to handle dynamic variables since the compiler will have to be capable of doing all the operations on all the constant variables just as if you were executing your program and it has to handle all the tests necessary to ensure integrity.

    So... we need a library that can handle integers, a library to handle floating points, a library to handle arrays, etc.

  • I just switched my websites from one server to another and noticed that on my main company site (http://www.m2osw.com) I would get a # at the end of the URL. Automatically added somehow. Thinking that could be a bad guy I checked the code and could not really see anything.

    Hitting "Back" once, I noticed that the # would be transformed to #atssh-digg. I don't have anything specific about digg on that page except the AddThis button. That adds Digg among some 150 different systems where you can share my pages.

  • Managing your own Drupal Download Site

    The other day, I was thinking, it would be nice if I could find the way to manage my own download site so people who use my modules that I do not provide directly on http://drupal.org would still show as expected (i.e. Green in the update window).

    I found this page about it: http://drupal.org/node/210984

    This is done by creating a service in your Drupal environment. You should use the ready made script named:

  • If you are running a webserver, you should use a webserver firewall. This prevents many attacks from being perpetrated on to your servers without the need to make your own applications more complex than necessary.

    The idea is very simple, if you have a few people who can edit your data from the Internet and those have a static IP address, you can check that the editor pages are only accessible to those IP addresses. Any other access can simply be blocked.

  • Error about a local certificate?!

    The other day, I got a new certificate from godaddy.com. I installed the certificate by replacing the files and simply restarting Apache. I then checked in Sea Monkey and it worked great. Checking the certificate it told me "valid for another 3 years."

  • Today we again ran in an out of memory error. As we are adding more websites our foot print is growing... Our servers use a VPS that has limited resources and whenever the limit is reached, the system automatically kills processes. How the VPS selects the process to kill isn't clear to me, but twice it has been our database manager meaning that all of a sudden all the websites stop working.

    So... We got an extra bit of RAM because our package allowed it, but that's still small.

  • How it works

    The at command is often used to start a process at a later time. It can run any script at a specified date and time.

    For instance, if you want the computer to send you a signal in one hour, use something like:

    cat signal | at -q z now + 60 minutes

    Assuming that the file named signal contains the commands necessary to generate the signal. Then in 60 minutes, the script will be execute and the signal will be heard or shown.

  • I had Ubuntu 6.04 and there were many errors about Audio drivers and devices not working. I turned it off and that was it at the time.

    Now that I have upgraded to Ubuntu 8.04 (avoiding the bug in October Debug in regard to a huge error in generating an SSL key and all of that!), I thought I'd try again.

    I use VLC so I tried to run with that. I could see the audio equalizer so I thought that it should be working and we should hear the audio... but nothing at all. And VLC would spit out an error about the pulse audio deamon not working properly:
